Specification forming part of Letters Patent No. 1 67,788, datedSeptemberl4, 1875; application filed April 17; 1875.

To all whom it may concern:

Be it known that we, WILLIAM RIoHMoND, THOMAS RYAN, and J AMns MoGILL,of Lockport, in the county of Niagara and State of New York, haveinvented a new and valuable Improvement in Smut-Hills; and we do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figuresof reference marked thereon.

Figure l of the drawings is a representation of a vertical centralsection of our mill, and Fig. 2 is a horizontal sectional view of thesame. Figs. 3, 4, 5, and 6 are detail views.

This invention has relation to improvement in smut-machines, for whichLetters Patent of the United States, dated January 5, 1875, and numbered158,524, were granted to William Richmond, as executor of JamesRichmond, deceased.

The object of the invention is to produce, by means of devicessubstantially as hereinafter described, an accurate and even adjustmentof the brushes to or from the inside of the scouring-case, thus adaptingthe device to be used in cleaning different varieties of grain.

In the annexed drawings, A designates a cylindrical shaft, upon whichare rigidly secured, preferably, metallic heads or spiders B B, the samebeing at a suitable distance apart, and-adapted, by means of guides ora, respectively, upon the upper head B and the lower head B, to receivethe projecting arm b of angular end plate 0, rigidly secured in anysuitable manner to the brush-backs D. Guides at a are arranged in pairs,and these pairs are equal in number to the number of brushes intended tobe used.

In practice, head B will be solid and cupshaped, its concavity beingupward and radially serrated for the purpose of distributing the grainevenly around the inside of the scouring-case, and the lower spider willbe open for the purpose of allowing air to penetrate into the interiorof the scouring-case.

Plates 0, as shown in Fig. 4, are each provided with an eye, 0, at theangle of the arms, for a purpose hereinafter fully explained. Q

D represents sliding spiders, arrangedupon shaft A, and adapted to havefree movement thereon, which spiders have a number of arms, 6, equal innumber to that of the brushes employed. Spiders D and angular plates 0are connected together by means of rods E of suitable length, which rodsare pivoted to the lug c and arm a, and the said spiders are eachprovided with a female-screw-threaded projection, f, the thread in oneof the projections being right-handed and in the other lefthanded. Frepresents a metallic rod passing upward through projections f, whichrod is threaded to correspond with the threads of the said projections,and is adapted to be rotated therein by means of an operating-handle, g,rigidly secured upon its lower end, which projects through thescouring-case. When this rod is caused to rotate in one directionsliding spiders D will be forced away from each other, thus forcing thebrushes radially outward against, or rather close to, the interior ofthe scouring-case through the medium of rods E, and when it is actuatedin the opposite direction the said slides will be drawn together,causing the said brushes to recede from the scouring-case, thus adaptingthem for use with different varieties of grain. This adjustment may behad without opening the scouring-case, as the end of rod]? projectsthrough and below it. With a view to holding rod F against endwisedisplacement during such actuation collarsi are rigidly secured thereonat a slight distance apart between screw-threads h, between which isreceived a bifurcation upon the end of an arm, j, forming a part of anannular sleeve or collar, Gr, clamped in position on shaft A by means ofa set screw, 8. H represent strengtheningstrips, rigidly secured uponthe brush-backs, having rounded or beveled inner edges, as shown in Fig.2. By this means dust scoured out of thegrain is prevented from lodgingon the backs of the brushes, and will be blown out of the spout in theusual well-known way, thus keeping the interior of the brush-frameclean, and preventing grain subsequently subjected' to the machine frombeing unduly contaminated.

Each brush, which I shall now designate 2 a i m'mss .bythe letter T, isprovided with the usual a well-known beaters K, the same being of metal,

and rigidly secured by means of screws 1' to guides at a, with theirouter edges flush with the corresponding edge of the brush-back, and

- extending the whole length thereof.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a smut-machine, the ways or guides a a, of heads B B, incombination with the angular plates 0 of the detachable and radially-movable scourer-brushes T, substantially as specified.

2. The angular plates 0, having lugs c and guides at, in combinationwith a scourer-brush, substantially as described, and forthe purpose setforth.

tially as specified.

.3. The connecting toggles E, in combination with the sliding spiders D,and plateO WILLIAM RICHMOND.
